Transistor Devices

Why did tube-based TVs continue to be manufactured throughout most of the 1960s?

As an antique radio collector I know that most tube-based models date before 1960. However many TVs manufactured throughout most of the 1960s continued to contain tubes. You would think manufacturers would switch quickly to exploit the demand for transistor devices.

I would think that the engineering and design from tube-based tv’s to transistor-based tv’s would have taken several years to occur. When the smaller transistors were designed into the schematics of tube-based tv’s, I would suspect that the designers didn’t quite know what to do with all that extra space.

It took even more years of development before integrated circuits replaced those modules laden with transistors, resistors, diodes, capacitors, etc., which still left the CRT to deal with.

Now look at us…HDTV’s in LCD, Plasma, LED-backed LCD’s. Whew!
